BUTr'oN-PoLlsHiNc MACHINE.

SECIFICATION forming part of Letters Patent No. 664,101, dated December 18, 1900.

Application filed July 11,1900.

To all whont it nfl/ty concern:

Be it known that I, JOHN A. SHOEMAKER, a

citizen of the United States, residing at La Salle, in the county of Niagara and State of New York, have invented new and useful Improve ments in Button-Polishing Machines, of 1 which the following is a specification.

This invention relates to a machine forbuff-v ing or polishing buttons, and embraces in its.

which carry the buttons and the carrier upon which the dies are mounted. f

Another object of this invention is to improve the construction of the dies and the carrier supporting the same.

Another objectI of my invention is to provide simple means for retaining the buttons on the dies preparatory to polishing the same and also to remove the same from the dies after being polished.

Another object of my invention is to improve the means for adjusting .the bufngwheel.

Another object of my invention is toprovide simple means for automatically applying wax to the bufflng-wheel.

My invention has the further object to improve the machine in several details of construction.

In the accompanying drawings, consisting of four sheets, Figure l is a side elevation of my improved button-bufling machine. Fig. 2 is a fragmentary horizontal section in line 2 2, Fig. l, showing the device for adjusting the button-ejector. Fig. 3 is a central longitudinal sectional elevation of my im proved buffing-machine, taken in line 3 3, Fig. 6.

Fig. l2 is a similar section in line l2 l2, Fig. l, showing part of the device whereby the buffing-wheel is adjusted backward and forward. Fig. 13 vis a fragmentary vertical section showing the means for polishing different sizes of buttons on the same spindles.

Lilie letters of reference refer to like parts `in the several figures.

The main frame of the machine consists, essentially, of a base A and two standards A A2, mounted on the base.

B represents the rotary bufting-wheel, of soft material, whereby the buttons are bu ffed or polished and which is mounted on a horizontal shaft B. The dies C, which support they buttons while being polished, are mounted on a rotary carrier D, arranged with its rear portion below the buffing wheel and mounted on an upright carrier-shaft E. The carrier consists of upper and lower journaldisksd d', connected by a hub cl2, which is secured to the carrier-shaft, and a supporting-plate d3, mounted loosely on the carriershaft above the upper journal-plate and resting on the latter. Each of the dies consists of a vertical spindle c and a ring or sleeve c2, surrounding the upper end of the spindle. The upper end of the spindle forms the bottom of the die, and this end of the spindle is preferably concaved, as shown at c', Fig. 7, so as to receive the convex under side of the buttons. When the die spindle and sleeve are in their proper relative position, the spindle is depressed, so that the upper part of the die-sleeve projects above the upper end of the spindle, thereby forming the side wall of the die, as shown at c3, Fig. 7. While the parts of the die are in this position, the operator places a button upon the same, which button rests with its under side on the spindle and with its edge against the inner side of the die-rim, whereby the button is confined upon the die while being carried past the IOO buiiing-wheel, and the projecting upper part of the button is polished by the wheel.

Vhen it is desired to polish buttons of largerdiameter, the small die-ring is replaced by a larger one corresponding to the size of the button to be polished, and a spacing-ring c4 is interposed between the die-spindle and the large die-ring, as shown in Fig. 13.

The carrier-shaft is journaled near its upper and lower ends in bearings e e', arranged on the front side of the standard A', and is driven from a horizontal driving-shaft F, arranged below the carrier-shaft, by a .pair of intermeshing bevel gear-wheelsff', mounted, respectively, on the driving-shaft and the lower end of the carrier-shaft. The gear- Ywheelfis splined on the driving-shaft, so as to permit the same to move lengthwise thereon, thereby enabling the gear-wheels ff to be engaged or disengaged for rotating the die-carrier or stopping the rotation thereof. The driving-shaft is provided at its outerend with a driving pulley e2, which receives a driving-belt. The die-spindles are arranged in an annular row around the carrier-shaft, and each spindle is journaled with its central part in bearings formed in the journalplates and projects with its upper end upwardly through an opening in the supporting-plate d3, as shown in Figs. 3, 6, and 7. The die-sleeve c2, which surrounds the upper end of each die-spindle, rests on the upper side of the supporting-plate d3. Each of the several die-spindles is rotated on its own axis by a master gear-wheel G, meshing with gearpinions g on the lower ends of the die-spindles, as shown in Figs. 3 and 6. The master gear-wheel G is secured to the upper end of a sleeve g', which is mounted on the carriershaft above the lower bearing thereof, as shown in Fig. 6. g2 is a driving-sleeve arranged on the driving-shaft and provided on its inner end with a bevel gear-wheel g3,which meshes with a bevel gear-wheel glon the lower end of the sleeve g'. The outer end of the driving-sleeve g2 is provided with a drivingpulley g5, whichreceivesa driving-belt. The driving-sleeve is capable of moving lengthwise on the driving-shaft for engaging its gear-wheel g3 with the gear-wheel g4 or disengaging the same therefrom for rotatingthe die-spindles orstopping the rotation thereof. The longitudinal movement of the drivingsleeve is effected by a shifting-lever gli, connected with a collar Q7, which is arranged in an annulargroove in the driving-sleeve. The bevel gear-wheel f is shifted lengthwise on the driving-shaft into its operative or inoperative position at the saine time that the gearwheel g3 is shifted into its operative or inoperative position by coupling-lugs g8, arranged on the innerside of the gear-wheel gand engaging with an annular groove in the hub of the gear-wheelf. This means of driving the carrier and the dies cause these parts to be turned positively, thereby insuring turning of the buttons while act-ed upon by the buffing-wheel, whereby burning or discoloring of the buttons is avoided,which otherwise would be liable to happen.

A vertically-reciprocating movement is imparted to each die-spindle for ejecting the bu tton from the die after the same is polished.

When the dies are arranged on the front side of the carrier, the die-spindles are lowered, so that the concave seats in the upper ends thereof are arranged below the upper ends of the die-rings, as represented in Figs. 3 and 7. While the dies are in this position the operator places the unpolished buttons upon the dies, each button resting with its convex under side against the concave top of the die-spindle and with its edge against the inner side of the ring, as represented in Figs. 3 and 7. The dies, together with the unpolished buttons supported thereon, are carried bodily by the carrier around the axis of the latter in the direction of the arrow, Fig. l0, and at the same time each die, together with the button supported thereon, rotates about its individual axis. As the dies and buttons move along the rear side of the carrier the rota ting bufling-wheel engages with its lower side against the top of the buttons, as represented in Fig. 3, and polishes the same. After the buttons have passed the bufng-wheel, during the continued rotation of the carrier, the die-spindles are successively raised, so that the concave upper end of each spindle is arranged above the die-ring, whereby the polished button is lifted from the die-ring preparatory to being removed therefrom by a discharging or sweeping device. The diespindle is preferably lifted for ejecting the button thereon while the die is arranged on the left side of the carrier. After the polished button has been removed from the diespindle the latter is lowered into its operative position preparatory to receive another unpolishcd button as it passes the front side of the machine.

The upward movement of the die-spindle is effected by a lifting-cam H, which is arranged in the path of the lower ends of the die-spindle, so that the latter, while moving bodily around the axis of the carrier, engage their lower ends successively with the liftingcam and are thereby lifted for discharging the buttons thereon. The cam is vertically adjustable, so as to permit the extent which the die-spindles are raised to be adjusted to suit the size or thickness of the buttons and also to compensate for any wear of the dies or the discharging device which removes the buttons from the dies. For this purpose the lifting-cam is arranged on the upper end of a vertically-movable plate h, which is raised and lowered by a rock-finger h', engaging between two lugs h2 on the cam-plate. The rock-finger is secured to a rock-sleeve h3, which passes through a vertical slot h4 in the cam-plate, and is mounted on a horizontal arbor h5, which projects forwardly from the standard A2, as shown in Figs. l, 2, 6, and l0.

IOO

IIO

The front end of the rock-sleeve is provided with a hand-wheel h6 for turning the same. The cam-plate is held in its adj usted position by a clamping-screw nut k7, arranged on the threaded front end of the arbor and bearing against the front end of a rock-sleeve, and a clamping-screw 718, passing through a vertical slot h9 in the cam-plate and entering the standard A2, as shown in Figs. 6 and 8. After the die-spindles clear the lifting-cam H the same drop by gravity into their lower operative position, the movement of the spindles in this direction being limited by shoulders hw on the spindles engaging with the upper side of the lower journal-plate d, as shown in Figs. 3 and 6. The teeth of the master gear-wheel G and of the pinions on the diespindles are sulicienl-ly long to prevent the same from becoming disengaged during the vertical movement of the spindles.

The die-rings are rotated by frictional contact with the die-spindles, and as these rings rest on the supporting-plate di the latter becomes worn bythe lower ends ofthe die-rings. By making the supporting-plate of the carrier separate from the journal-plates the supporting-plate when worn considerably can be easily removed and replaced by a new one without necessitating the renewal of the journal-plates which contain the bearings of the spindles.

The discharging device for removing the polished buttons from the dies consists, preferably, of a rotary brush I, which is arranged above the die-spindles at the place where the same are raised by the lifting-cam. This brush is turned so that its lower part moves outwardly, whereby the buttons when lifted into engagement with the brush are swept outwardly by the latter from the top of the die-spindle. The buttons which are removed from the dies are discharged into a spout z', whereby the buttonsare conducted into a receptacle. The delivery-brush I is journaled in a bracket i', secured to the upper bearing e of the carrier-shaft, as shown in Figs. 6 and lO. Motion is imparted to the delivery-brush by any suitable means-forinstance,as shown in Figs. 1, 6, and 10 by means of a frictionwheel 2, which is rotated by engaging with the top of the supporting-plate, a pair of intermeshing gear-wheels t3, arranged on the friction-wheel shaft and a counter-shaft 114, and a pair of intermeshing bevel gear-wheels i5, secured to the brush and counter-shaft, as shown in Figs. l, 6, and l0.

J represents a horizontal guard or retaining plate whereby the buttons are prevented from becoming displaced or dislodged from the dies by the suction or blast of the buftingwheel while the buttons are carried forward and from the bung-wheel. The retainingplate has the shape shown in Fig. 1l andis arranged close to the top of the buttons on the receiving and delivery sides of the buffing-wheel, as shown in Fig. 6, so that the buttons are held on the dies and prevented from being dislodged therefrom by the blast or suction of the bung-wheel. The buttons are sometimes placed improperly by the operator on the dies, so that they project too far above the same. In order to prevent these misplaced buttons from being injured while passing underneath the retaining-plate and also to straighten the buttons in the dies, the retaining-plate is yieldingly supported, so as to permit the same to yield upwardly. The yielding support for this purpose shown in the drawings consists of vertical guiderods j, connected at their lower ends to the retaining-plate and passing freely with their upper ends through lugs j', arranged on the upper bearing of the carrier-shaft, and a springjz, surrounding cach guide-rod between the guide-lug and the top of the retainingplate, as shown in Figs. l, 8, 6, and l0. The downward movement of the retaining-plate is limited by screw-nuts js, arranged on the upper screw-threaded ends of the guide-rods and bearing against the top of the guide-lugs. By screwing the nuts up or down on the guiderods the position of the retaining-plate may be adjusted to suit different thicknesses of buttons or to compensate for the wear on the dies. The retaining-plate is centered on the carrier-shaft by a hook 3'4, arranged on the front part of the plate and embracing the carrier-shaft, and a cross-barj5, which is secured across the opening of the hook so as to confine the retaining-plate on the carriershaft, as shown in Fig. ll. The retainingplate is held against turning with the carrier, but is permitted to move vertically by a vertical pin j, which is secured to a stationary table f or other support arranged adjacent to the carrier and which projects upwardly through a perforated ear js on the ad jacent part of the retaining-plate, as shown in Figs. 6, l0, and l1.

For the purpose of permitting the bungwheel to be raised or lowered or moved backward or forwardfor adjusting the buffingwheel to suitdifterent sizes of buttons or for taking up wear of the wheel an adjusting mechanism is provided, which is constructed as follows:

K K represent' two upright supportingarms provided at their upper ends with bearings c, in which one end of the shaft of the butng-wheel is journaled. The lower ends of the supporting-arms K K are arranged on opposite sides of the standard A2 and are pivoted by horizontal screws 7f3 to a cross-head k2. The latter is guided in vertical ways k3 in the standard A2. By raising or lowering the cross-head1@2 the upper ends of the supporting-arms, together with the bnfting-wheel mounted thereon, may be moved upward or downward, and by swinging the upper ends of the supporting-arms forward or backward, together with the bufling-wheel, the latter may be adjusted to the position which the size or character of the buttons require in order to buff or polish the same properly. The

IOO

IIO

vertical adjustment of the cross-head 7a2 is effected by a vertical screw-shaft 7a4, which is journaled at its ends in bearings on the standard A2 and which works in a screw-threaded opening in the cross-head 71:2, as shown in Fig. 9. The screw-shaft is turned in either direction for raising or lowering the cross-head by an upright shaft 755, journaled in bearings 7o on the main frame and connected atits lower` end with the screw-shaft by intermeshing gear-wheels k7, while its upper end is provided with a hand-wheel ks, as shown in Figs. l, 6, 8, and l0.

L representsa horizontal screw-shaft whereby the buffing-wheel is adjusted backward or forward and which is arranged lengthwise on one side of the buiiing-wheel. This shaft engages with its screw-threaded rear end in a swiveling screw-nut Z, which is pivoted 0n a post Z, arranged on the rear part of the base. The screw-shaft L is journaled near its front end, but held against lengthwise movement in a swiveling bearing Z2, which is pivoted on the upper end of one of the supporting-arms K. Upon turning the screw-shaft L in one direction or other the upper ends of the supporting-arms are moved backward or forward. The screw-shaft L is turned by means of a shifting-sleeve Z3, which is provided with a hand-wheel Z4and which is keyed or splined on the screw-shaft in front of its swiveling bearing Z2 by a pin Z5 on the shaft passing through longitudinal slots Z6 in the sleeve. The screwshaft L is held in position after adjustment by a shoulder Z7 on the shaft bearing against the rear side of the swiveling bearing and a clamping-screw ZS, which is arranged on the screw-threaded front end of the shaft and which presses the shifting-sleeve Z3 against the front side of the swiveling bearing Z2, as shown in Fig. 12. The buffing-wheelis rotated in the direction of the arrow, Fig. 3, by a belt M, passing around a driving-pulley m on the driving-shaft m' and a pulley m2 on the bulng-wheel shaft B and also around intermediate pulleys m3 m". The intermediate pulley m3 is mounted on a shaft m5, which is journaled in bearings arranged on arms m6, projecting rearwardly from the main standard A', as shown in Figs. l and lO. The other intermediate pulley m4 is mounted on an upright adjusting-lever N, which is pivoted at its lower end, so that it can be swung forward or backward for adjusting the tension of the driving-belt M. The adjusting-lever is held in position after adjustment by aspring-catch n, pivoted on the lever and engaging with one of a longitudinal row of teeth n on a horizontal catch-bar n2.' The latteris pivoted at its rear end on the upper end of the post Z and rests with its front end on a lug or pin n3, arranged on the tightener-lever N, adj acent to the catch of the latter. Upon shifting the le ver backward or forward the catchbar rises or falls, so as to adjust itself to the changing position of the tightener-lever.

O represents a delivery pipe or conduit whereby the particles of dust and dirt which are removed from the buttons while polishing the same are carried away. The bufiingwheel is arranged in the front end of this pipe and projects downwardly through the opening in the front end thereof into engagement with the buttons which are carried past the same. The bufling-wheel is detachably secured to its shaft between a collar p, fixed 011 the shaft and bearing against one side of the wheel, and a detachable collar p', which is pressed against the opposite side of the wheel by a screw-nntp2 on the shaft. In order to permit of conveniently applying the buffing-wheel to its shaft and removing the samel therefrom, the front end of the dustpipe is provided with a movable side portion o, which is arranged on one side of the buff ing-wheel, and a movable top portion o2,which is arranged above the buiing-wheel. These movable sections are hinged at their rear ends to the main part of the dust-pipe, and when swung outwardly they form an opening in the top and side at the front end of the dustpipe which affords access to the bufling-wheel.

Q represents arotary fan which is arranged in an enlargement of the dust-pipe in rear of the bufng-wheel, as'shown in Figs. 3 and 10, and which assists the buiing-wheel in conducting the dust rearwardly through the dustpipe. The fan is mounted on the shaft m5of the intermediate pulley which extends across the dust-pipe, whereby the driving-belt M drives the buiiing-wheel and fan at the same time and in the same direction.

For the purpose of waxing the buiiing-wheel without requiring the attention of the operator 'an automatic waxing device is provided, which is constructed as follows:

R represents a gear-wheel which meshes with a gear-wheel Ron the upper end of the carrier-shaft and which is provided on its upper side with two wax-holders r. These wax-holders are rotated from the carrier-shaft by the gear-wheels R R and are so arranged that each holder rubs the piece of wax which it holds against the periphery of the buflingwheel at the receiving side thereof, thereby leaving the periphery of the buiiing-wheel on the delivery side thereof unwaxed, whereby the buttons as they are carried past the buffing-wheel are first subjected to a harsh treatment for removing the dust and dirt therefrom and then receive a comparatively gentle treatment for nishing the face of the buttons. One wax-holder is preferably provided with wax containing grit which causes the bufiing-wheel to produce an abrading action upon the buttons, while the other holder is provided with a piece of smooth Wax which causes the buing-wheel to produce a polishing action on the buttons. The gear-wheel R', which carries the wax-holders, is journaled on a rock-arm 7^', which is pivoted on the carrier-shaft, as represented in Figs. l, 4, and 6, whereby these Wax-holders may be adj usted toward and from the buiiing-wheel for IOO IIO

taking up the wear on the wax or on the bn ffing-wheel wil hout disturbing` the dri vinggear. The adjustment of the rock-arm r is effected by an adjusting-rod r2, which is pivoted at its rear end to the rock-arm and passes with itsfront end loosely through a guide-lugrou the upper bearinge,aud screwnuts r4 r4, arranged on the adj usting-rodr on opposite sides of the guide-lug rs, as shown in Figs. 1, 3 to 5, and 10.

It will be observed that the various adjusting devices are arranged? within convenient reach of the operator while the latter stands at the front of the machine and permits of adjusting the several parts while the machine is running.
